WIDEBAND ELECTRODYNAMIC TRANSDUCER FOR AUDIO HELMET AND AUDIO HELMET

摘要

An electrodynamic transducer (10) for broadband audio headphones, said transducer (10) comprising: - a magnetic motor (11) configured to generate a magnetic field; - a coil (12) disposed in an air gap (13) of said magnetic motor (11) and movable in translation under the effect of said magnetic field; and - a membrane (14) connected to said coil (12) so as to convert the translational movement of said coil (12) into an acoustic wave; said transducer (10) comprising a self-supporting coil (12) bonded to said membrane (14), said membrane (14) having a Young's modulus greater than 40 GPa.
